LOS ANGELES - Teena Marie, the "Ivory Queen of Soul" who developed a lasting legacy with her silky soul pipes and with hits like "Lovergirl,""Square Biz," and "Fire and Desire" with mentor Rick James, has died. She was 54. The confirmation came from a publicist, Jasmine Vega, who worked with Teena Marie on her last album, 2009's "Congo Square." Her manager, Mike Gardner, also confirmed her death to CNN. The singer continued performing in recent years after overcoming an addiction to prescription drugs. It was unclear late Sunday where and how she died. Marie certainly wasn't the first white act to sing soul music, but she was arguably among the most gifted and respected, and was thoroughly embraced by the black audience.
